Move restoring LOOKUP_PARENT and zeroing nd->stack.name[0] past the call of get_link() (nothing _currently_ uses them in there). That allows to moved the call of may_follow_link() into get_link() as well, since now the presence of LOOKUP_PARENT distinguishes the callers from each other (link_path_walk() has it, trailing_symlink() doesn't). Preparations for folding trailing_symlink() into callers (lookup_last() and do_last()) and changing the calling conventions of those. Next stage after that will have get_link() call migrate into walk_component(), then - into step_into(). It's tricky enough to warrant doing that in stages, unfortunately...

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
